Doran et al. ◀ Dinosaur baraminology ▶ 2018 ICC 430 Figure 52. Biplot of PCA scores (black) and vectors (gray) for Upchurch et al.’s (2004) data matrix for Sauropoda. PC 1 accounts for 61.8% of the variance and PC 2 accounts for 16.6% of the variance. In contrast to the BDC or MDS results PCA ordinations suggest additional discontinuity between Diplodocoidea (specifically Flagellicaudata) members (top left) and other sauropods. Figure 53. BDC results for Norman, Witmer et al.’s (2004) data matrix of “basal” Thyreophora, as calculated by BDISTMDS (relevance cutoff 0.85). Closed squares indicate significant, positive BDC; open circles indicate significant, negative BDC. Figure 54. Three-dimensional classical MDS applied to Norman, Witmer et al.’s (2004) data matrix for “basal” Thyreophora. Scelidosaurus , Scutellosaurus , and Emausaurus are shown in gray (center), Lesothosaurus (orange) and Cerapoda (light orange) and the outgroup (red) are toward the right, while Eurypoda ordinates toward the far left (dark orange). The scree plot shows the first axis explains the majority of the variation. Figure 55. Biplot of PCA scores (black) and vectors (gray) for Norman, Witmer et al.’s (2004) data matrix for “basal” Thyreophora. PC 1 accounts for 76.9% of the variance and PC 2 accounts for 21.1% of the variance. Eurypoda is isolated the top left.
